What are the 'Meer' (the lovers) of those mirror-like faces, who appear bewildered when leaving home.

This couplet is a profound observation on deceptive appearances. Mir Taqi Mir suggests that you shouldn't expect much from those whose faces are like mirrors—beautiful, reflective, but ultimately transient. They leave the house looking utterly bewildered or different from who they were. It speaks to the fleeting nature of beauty and the constant mask we wear in society, suggesting that true authenticity is rarely found in superficial glamour.
